Jun 12, 2006· Jets of water are being directed onto a gravel slope in a mining process known as sluicing. The water washes down fine gravel containing gold so that it can be directed into sluice boxes and recovered using gravity separation (where the heavy gold is trapped at the bottom and the lighter sands are washed away).
The North Mara gold deposits are situated in the Mara Musoma greenstone belt. There are several types of gold mineralisation including shearzonerelated quartz vein and disseminated gold. The mine is a combined open pit and underground operation from two deposits, Gokona (underground) and .

Using gravity and water to separate the dense gold from the other materials that surround it, this is the most common gold mining category for amateur gold hunters. Hard rock mining is the process of using open pit or underground mining tunnels to retrieve the gold from the rock.
While gold sourcing is often referred to simply as "mining," mining is, in fact, just one piece of the production puzzle. The process of obtaining gold is actually multifaceted and can be more or less summed up in four steps: prospecting, mining, extracting and refining.

This process is continued until only heavy "black sands" (such as ilmenite, magnetite, and pyrite) and gold remain. The material is dried and the gold removed (perhaps after using a magnet to remove some of the black sand). Panning is slow, backbreaking work, but in experienced hands there is little or no loss of gold. See also placer mining.
